联合国大会的社区结构
Community Structure in the United Nations General Assembly
摘要：
我们研究了代表联合国大会决议投票的网络的社区结构。我们以三种不同的方式从1946年至2008年的单独年度会议的投票记录中构建网络：（1）将投票相似性视为加权单部网络;（2）将投票相似性视为加权签名单部网络;（3）通过检查签名双部网络，其中国家与决议有关。对于每一个配方，我们通过使用适当的空模型优化网络模块化来检测社区。我们比较和对比的结果，我们得到这三种不同的网络表示。在这样做的时候，我们说明了需要考虑多个分辨率参数，并探讨每个网络表示的有效性，以确定投票组中的大量协议中典型的大会投票。
英文摘要：
We study the community structure of networks representing voting on resolutions in the United Nations General Assembly. We construct networks from the voting records of the separate annual sessions between 1946 and 2008 in three different ways: (1) by considering voting similarities as weighted unipartite networks; (2) by considering voting similarities as weighted, signed unipartite networks; and (3) by examining signed bipartite networks in which countries are connected to resolutions. For each formulation, we detect communities by optimizing network modularity using an appropriate null model. We compare and contrast the results that we obtain for these three different network representations. In so doing, we illustrate the need to consider multiple resolution parameters and explore the effectiveness of each network representation for identifying voting groups amidst the large amount of agreement typical in General Assembly votes.
